IMPROVEMENT IN MACHINERY FOR FORNIING HEEL-BLANKS.

Specification forming part of Letters Patent No. 149,056, dated March31, 1:74; application .tiled March 7, 1874.

To all whom it may concern:

Be it known that I, LEANDHR M. NUTH, of Great Falls, in the county ofStratford and State of New Hampshire, have invented certain new anduseful Improvements in Heel- Fitting Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains -to make and use it, reference being had to the accompanyingdrawings, which form part of this speciiication.

My invention relates to improvements on machines for fitting heels forboots and shoes, and consists in the employment of a hookedpresser-foot, operated by means of a foottreadle and a spring, or itsequivalent, in combinationwith a pair of adjustable guide-pins thatproject above the work-plate a distance equal to the thickness oftheheel that is to be fitted together, in a manner as will now be morefully shown and described.

On the drawing, Figure l represents a front elevation of my invention.Fig. 2 represents a ground plan. Fig. 3 represents a centrallongitudinal section on the line A B, (shown in Fig. 1;) and Fig. 4represents a vertical section on the line C D, (also shown in Fig. l.)

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

In fitting heels for boots and shoes, it is desirable that all of themshould be of equal thickness, and to accomplish this object rapidly, andin such a manner that the operator shall have both hands ready for thepicking up of the material and fitting it together, I make use of thefollowing invention:

a represents a post or standard, secured to the floor or otherwise, asmay be convenient. To the top of said'standard a is secured a metallicwork-supporting plate, b, as shown. Through the front of the plate b isthe presser-foot bar c, made to slide up and down. The downward motionof the said bar is obtained by pressure from the operators foot on thetreadle-lever d, to which the lower end of the bar c is connected in asuitable manner.

The treadle-lever d is made to move on a fulcrum, c, arranged, in asuitable manner, in connection with the lower end of the standard a, asfully shown in Fig. 3. When the pressure on the treadle d is removed,the bar c is raised automatically by means of the coiled spring j', thatsurrounds the bar c, and is secured in its lower end thereto, and in itsupper end to the work-supporting plate b, as shown. The upper end of thebar c extends horizontally as a presser-foot, g, (shown in Fig. 3,) andserves for the purpose of pressing the dilierent layers together ofwhich the heel is composed, and for the purpose of holding them in theirproper relative position till they are nailed together by the operator.A pair of adjustable guides, h It, are arranged on each side of thepresserfoot g, and can easily be made to project more or less above thework-supporting plate b by the turning of the set-screws t' t', andtheir check-nuts k 7u. The guide-pins 7L h should project above thework-supporting plate b a distance equal to the thickness of the desiredheel that is to be made. Should the combined thickness of the layersconstituting a -heel be a little larger than the projecting parts of theguides h h, the heel parts can easily be pressed together, by means ofthe presser-foot g, previous to nailing the heel parts together.

The operation of my machine is as follows: The guide-pins h h areadjusted to project above the plate I) a distance equal to the desiredthickness of the heels. rIhe operator picks up and places heel-piecesover each other on the plate b till their combined thicknesses are equalto the projecting parts of the guides It h, when the presser-foot g ismoved down on the heel, so as to hold it in position for the purpose ofnailing and clinching it together. As soon as the heel is nailedtogether, the operator relieves the pressure on the treadle d, when thespring f causes the presser-foot g to rise above the heel, when it isquickly removed by the operator, and a new one commenced with in asimilar manner.

Having thus fully described the nature,

construction, and operation of my invention, In testimony that I claimthe foregoing7 I I wish to secure by Letters Patent, and have hereuntoset my hand this 25th dey of claim- February, 1874.

In combination With the standard co and its T plate I), the presser-footc g, lever d, spring; LEANDER M' LUTE' f, and the adjustable guide-pinsh h, With Vtnesses: their screws i 'L' 'and check-nuts k 7c, as and forALBAN ANDRN, the purpose shown and described. GEORGE E. PHELPS.
